From b0edba2af7154c82c28a4828f483c102ab201326 Mon Sep 17 00:00:00 2001 From: Jeremy Sowden Date: Fri, 13 Sep 2019 09:13:02 +0100 Subject: netfilter: fix coding-style errors. Several header-files, Kconfig files and Makefiles have trailing white-space. Remove it. In netfilter/Kconfig, indent the type of CONFIG_NETFILTER_NETLINK_ACCT correctly. There are semicolons at the end of two function definitions in include/net/netfilter/nf_conntrack_acct.h and include/net/netfilter/nf_conntrack_ecache.h. Remove them. Fix indentation in nf_conntrack_l4proto.h.

The structs and typedef themselves are defined by linux/netfilter.h but only when CONFIG_NETFILTER is enabled. Define them unconditionally and add forward declarations in order to remove CONFIG_NETFILTER conditionals from the other headers.
